A new process to control the shape of molten metal rivulet flow is proposed in which direct electric and magnetic fields are imposed directly on molten metal to induce electromagnetic force. The experimental works were carried out to clarify the characteristics of shape control function of electromagnetic force in rivulet flow. It was found that electric current and flow velocity are the most important factors in this process. It is noticed that this process can control the shape of molten metal more dynamically than previously proposed process in which only magnetic field is imposed. The experimental data verify a mathematical model which can predict the shape of rivulet flow from the conditions of electric current, magnetic field and flow velocity. The fact that height and width of the flow have good correlation with Stuart number indicates that this rivulet flow is dominated by inertia force and electromagnetic one.
